Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, from a base station, downlink control information that indicates a wakeup signal for a broadcast or multicast (broadcast/multicast) session in a session-specific field of the downlink control information. The user equipment may selectively perform, for the broadcast/multicast session, a wakeup operation for a discontinuous reception cycle based at least in part on the wakeup signal. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration signal configuring a set of random access opportunities over which to transmit a preamble associated with a random access procedure, each random access opportunity associated with a set of one or more uplink data opportunities. The UE may identify a repetition parameter for an uplink message. The UE may select a random access opportunity from the set of configured random access opportunities for transmitting the preamble based at least in part on the repetition parameter. The UE may transmit the preamble on the selected random access opportunity. The UE may transmit one or more repetitions of the uplink message based at least in part on the set of one or more uplink data opportunities associated with the selected random access opportunity.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit, and a user equipment (UE) may receive, configuration information related to a random access procedure. For example, in some aspects, the configuration information may include a physical random access channel mask configuration based at least in part on a random access occasion density in a time and frequency domain in a cell served by the base station, a random access response configuration based at least in part on an indication transmitted from the UE to the base station, and/or the like. Accordingly, the UE may perform the random access procedure based at least in part on the configuration information, which may be indicated to the UE in system information, radio resource control signaling, and/or the like. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for port selection for channel state feedback with analog feedforward. A method that may be performed by a user equipment (UE) includes selecting one or more channel state information reference signals (CSI-RS) ports, of a plurality of CSI-RS ports, for the UE to report CSI. The port selection includes selecting any of the plurality of CSI-RS ports for selecting CSI-RS based on a grouping of the plurality of CSI-RS ports. The UE determines a precoding matrix indicator (PMI) formed by a linear combination of the one or more selected CSI-RS ports. The UE computes at least wideband linear combination coefficients for the selected CSI-RS ports. The UE provides the selected one or more CSI-RS ports and the computed wideband linear combination coefficients to a base station (BS) in a CSI report.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiver of orbital angular momentum (OAM) multiplexing based communication may receive, from a transmitter of the OAM multiplexing based communication, a plurality of reference signals corresponding to a plurality of aperture pairs, wherein a reference signal of the plurality of reference signals corresponds to an OAM mode of a corresponding aperture pair; transmit, to the transmitter, a feedback message comprising beamforming information based at least in part on the plurality of reference signals; and receive, from the transmitter, a plurality of data streams that are beamformed based at least in part on the beamforming information. Numerous other aspects are provided.

Abstract: Technologies and techniques for wireless communication between a scheduled entity and a scheduling entity in a wireless communication network. A scheduled entity receives a downlink (DL) reference signal (RS) from the scheduling entity on a channel between the scheduling entity and the scheduled entity. The scheduled entity obtains channel state information (CSI) for the channel between the scheduling entity and the scheduled entity using the received DL RS, selects an uplink resource associated with a random-access procedure, and multiplexes a CSI report including the CSI with a random-access message related to the random-access procedure to produce multiplexed information.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques are described herein for encoding downlink control information (DCI) based on the number of transport blocks being scheduled by the DCI. The number of transport blocks supported by the DCI may be indicated explicitly using a field included in the DCI. The number of transport blocks can be implicitly signaled in a bitstream of the DCI block. The type of encoding scheme may be based on the coverage enhancement (CE) mode associated with a user equipment.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify a slot format configuration, such as a time division duplex (TDD) slot format configuration, and one or more downlink repetition configurations corresponding to a number of downlink repetitions for a user equipment (UE). The base station may transmit the configurations to the UE. The UE may determine that the number of downlink repetitions and the configured slot format satisfy, or fail to satisfy, a validation rule for monitoring the number of downlink repetitions. The UE may monitor, or refrain from monitoring, the number of repetitions based on whether the validation rule is satisfied.
